NEW YORK, NY - APRIL 25: Curtis Granderson #3 of the New York Mets celebrates with Jenrry Mejia #58 after hitting a walk off single in the bottom of the ninth inning to beat the Miami Marlins at Citi Field on April 25, 2014 in the Flushing neighborhood of the Queens borough of New York City.

The slumping Granderson grounded an RBI single to cap an improbable two-run rally with two outs in the ninth inning that sent the Mets past the Miami Marlins 4-3.

"Anytime you get a chance to win and jump up and down with your teammates, it's a good thing," Granderson said.

Granderson was 0-for-4 when he stepped to the plate with the scoreboard showing his batting average at .130. Not quite what anyone expected for a former All-Star fresh off a $60 million, four-year contract.

Lucas Duda led off the ninth with a soft single and moved up on a sacrifice.

Left fielder Christian Yelich made a nice running catch on pinch-hitter Bobby Abreu's liner for the second out. Omar Quintanilla followed with a single down the line and Yelich slipped on the dirt as he got ready to throw home, letting Duda score standing up.

Pinch-hitter Kirk Nieuwenhuis doubled to put runners at second and third. Granderson then grounded his game-winner past Jones at first base.

White Sox 9, Rays 6: Jose Abreu hit a walk-off grand slam, his second home run of the game, to lead Chicago.

Rules clarification: Baseball's Playing Rules Committee clarified the meaning of when a fielder catches the ball, saying possession was defined as having complete control of the ball. The committee said fielders may drop the ball after opening their gloves to make transfers.
